;;
|
||||
;; NOTE: THESE APIs ARE OBSOLETE:
|
||||
;;
|
||||
;; Databases of various forms can all be searched. These routines
|
||||
;; cover many common forms of searching.
|
||||
;;
|
||||
;; There are three types of searches that can be implemented:
|
||||
;;
|
||||
;; Basic Search:
|
||||
;; These searches allow searching on specific attributes of tags,
|
||||
;; such as name or type.
|
||||
;;
|
||||
;; Advanced Search:
|
||||
;; These are searches that were needed to accomplish some tasks
|
||||
;; during in utilities. Advanced searches include matching methods
|
||||
;; defined outside some parent class.
|
||||
;;
|
||||
;; The reason for advanced searches are so that external
|
||||
;; repositories such as the Emacs obarray, or java .class files can
|
||||
;; quickly answer these needed questions without dumping the entire
|
||||
;; symbol list into Emacs for a regular semanticdb search.
|
||||
;;
|
||||
;; Generic Search:
|
||||
;; The generic search, `semanticdb-find-nonterminal-by-function'
|
||||
;; accepts a Emacs Lisp predicate that tests tags in Semantic
|
||||
;; format. Most external searches cannot perform this search.
